Alternative names

Native range
Myanmar, Ayeyarwady drainage.
Natural habitat
Shallow, clear, plant-rich waters. In captivity use a mature planted tank with fine substrate, leaf litter or low cover, gentle-to-moderate movement and good oxygenation.
Diet & feeding
Micro-predator/omnivore. Offer small quality dry foods with regular Artemia, daphnia, cyclops and other suitably sized live/frozen foods.
Breeding & sexing
Research-backed guidance for identifying sexes and reproductive behaviour.
Sexing
Mature males are typically more intensely orange-red; females are fuller-bodied.
Breeding
Can spawn in planted aquaria; tiny eggs/fry are vulnerable to adults and filtration. Dense fine-leaved plants or spawning media improve fry survival.
